kicker 08zx350.2 wont turn on. something internal?

[Big-J]

i need some real help here. my amp will not power up most of the time. and when it does the right channel output transistors get very hot then switches in and out of protect mode leaving me to believe the problem is somewhere on the power supply end of the circuit board. no its not something simple like a ground, remote, or fuse. i have repaired amps before for the more common problems such as transistors but this is a little over my head. my first thoughts were that maybe there was a fault in the thermal protection circuit but it seems to work fine when the transistors over heat so i have no clue what it might be. might best guess would be failed capacitors but as i said before its kinda out of my realm of expertise. any help would be greatly appreciated
